STOVEPIPE-CLAM P.

SPECIFICATION forming part of Letters Patent No. 591 ,480, dated October 12, 1897. Application filed September 15, 1896- Serial N0. 605,858. (No model.)

To aZZ whom it may concern.-

-Be it known that I, FREDERICK-H. LIVINGS- TON, a citizen of the United States, residing at Ithaca, in the county of Tompkins and State of New York, have invented, certain new and useful Improvements in Stovepipe- Olamps; and I do declare the following to be a full, clear, and exact description of the in- Figure l is a perspective viewof my improved clamp applied to a section of stovepipe. Fig. 2 is a longitudinal section of the same, and Fig. 3 is a transverse section.

A represents the stovepipe, and B the cylin .drical collar, provided with a flaring mouth or flange B, which covers the hole in the wall or chimney. This flange B may be made at a right angle to the collar, if desired. The

cylindrical collar B is provided with two contiguous ears I) b on the opposite lapping edges of the collar, and they extend parallel and radially outward, being perforated to receive an adjusting bolt .and nut c, by means of. which the collar is rigidly adjusted to the stovepipe. The cylindrical lapping edges of the collar between the ears and the flaring for a short distance, thence upwardly at a right angle to form the arm 4, thence forwardly at an angle to the point 3, forming a brace 5, the whole being somewhat similar to the figure of a right-angle triangle.

Fig. 2 shows very clearly the manner of using the device, the wall or chimney being represented by the numerals 6 6.. The pipe being inserted in the hole, the clamp 1 is then pulled forward until its arm 4: rests against the opposite side of the wall. The collar is then pushed up until its flange rests against the inside of the wall and the perforations e engage one of the projecting teats on the clamp. The bolt and nut are then tightened, which draws the ears of the collar together, the overlapping edges slipping one over the other, allowing the collar to contract and rigidly secure the clamp, collar, and pipe together. When in this position in the wall, the arm 4 prevents the pipe beingdrawn inwardly, while the flange B prevents its further passage outwardly.

Although I have specifically described the construction and relative arrangement of the several elements of my invention, I do not desire to be confined to the same, as such changes or modifications may be made as Without departing from the spirit thereof.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, 1s

As 'an improved article of manufacture, a clamp for stovepipes, comprising the cylindrical collar B, formed with the integral flaring flange B, and having overlapping'edges, provided with integral parallel ears I) b, and alined perforations e, in combination with the longitudinal clamp 1, formed with a longitudinal seriesof raised teats 2 2, and the integral right-angular arm 4, the whole constructed and arranged substantially as shown and described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
